Abstract

Introduction: Non-small cell lung cancer (NSCLC) is a cancer with increasing morbidity and mortality in Vietnam. Molecular assays of EGFR, KRAS are widely used to guide individualized treatment in NSCLC patients. Objective: To investigate subclinical features and frequency of EGFR, KRAS mutations in patients with non-small cell lung cancer in University medical center HCMC. Materials and Methods: DNA was isolated from 111 FFPE samples collected from NSCLC patients. DNA libraries were sequenced on NextSeq instrument (Illumina). Results:  According to NGS results, mutations were detected in EGFR (52/111, 46,8% of patients), KRAS (16/111, 14,4%). EGFR mutations were frequent in women, <60 years old, adenocarcinoma. EGFR mutations were frequent in women, <60 years old, adenocarcinoma. Meanwhile, KRAS mutations were frequent in men, ≥ 60 years old, adenocarcinoma. Conclusions: NGS allows for specific detection and precise identification of gene mutations in NSCLC patients.
